花生种子黄酮及多酚含量的生态差异分析

为探讨生态环境是否对花生种子黄酮及多酚产生影响,及两者变化与初生代谢物脂肪和总糖含量变化的相关性,选用全国广泛栽培的、种子黄酮及多酚含量具有极显著差异的花生品种16个,在多个试验点进行2年种植,鉴定种子总黄酮、总多酚、脂肪和总糖含量,结果表明,基因型效应显著影响花生种子黄酮及多酚含量,濮花23号为高TFC品种,豫花9327为高TPC品种。生态环境对花生种子黄酮及多酚含量具有极显著效应,合肥试验点为适于黄酮和多酚形成的种植区。此外,黄酮及多酚二次生代谢物与脂肪、可溶性蛋白和总糖等初生代谢物在地域间变化趋势年纪间不一致。

Ecologic Difference of Flavonoid and Polyphenol Content in Peanut Seeds

In order to explore the ecological environment impact on peanut seed flavonoids and polyphenols,and the correlation between their changes with changes of fat and total sugar content,16 widely cultivated peanut varieties which were significantly different in flavonoid and polyphenol content,were planted in several test locations for two years.Total flavonoids content,total polyphenols content,fat content and total sugar content of peanut seeds were evaluated.The results showed that the genotype effect significantly affected the content of flavonoids and polyphenols in peanut seeds.Puhua 23 was a high TFC variety and Yuhua 9327 was a high TPC variety.The effects of ecological environment on the content of flavonoids and polyphenols were significant,and Hefei was the most suitable planting areas for forming flavonoid and polyphenol.The effect of temperature and precipitation was also significant.In addition,the corresponding trend between the secondary metabolites (flavonoids and polyphenols)and primary metabolites (fat, soluble protein and total sugar) among the locations were different between two years.
